Ok you don't have to worry about torrents but people expect pretty much 100% uptime on electrical service and you are dealing with transmitting an insane amount of energy which is technically non-trivial and can be extremely dangerous. You have to worry about power plant failure, maintenance, load balancing renewable and fossil fuels, meeting peak demands(rather than just slowing down everyone) and so on.
